Chromatin Modifying Agents Promote the Ex Vivo Production of Functional Human Erythroid Progenitor Cells Researchers have developed an ex vivo generated transfusion products composed of erythroid progenitor cells and precursors cells. [Blood] Predicting Clonal Self-Renewal and Extinction of Hematopoietic Stem Cells Results indicate that each hematopoietic stem cell (HSC) is programmed to have a finite life span. This program and the memory of the life span of the mother HSC are inherited by all daughter HSCs. In contrast, there was extensive heterogeneity in life spans between individual HSC clones. [Proc Natl Acad Sci U S A] Alveolar Epithelial Cell Therapy with Human Cord Blood-Derived Hematopoietic Progenitor Cells Researchers investigated the capacity of human umbilical cord blood-derived CD34+ hematopoietic progenitor cells to regenerate injured alveolar epithelium in newborn mice. [Am J Pathol] Human T Cell Development in the Liver of Humanized NOD/SCID/IL-2R(Gamma)null (NSG) Mice Generated by Intrahepatic Injection of CD34+ Human (h) Cord Blood(CB) Cells Results demonstrate that the intrahepatic injection of hCD34+ CB cells can facilitate human T cell development in the livers of humanized NSG mice. [Clin Immunol] Synergistic Effects of Growth Factors and Mesenchymal Stromal Cells for Expansion of Hematopoietic Stem and Progenitor Cells The supportive effect of mesenchymal stromal cells on hematopoiesis can be significantly increased by addition of specific recombinant growth factors – especially in combination with stem cell factor, thrombopoietin and fibroblast growth factor 1. [Exp Hematol] Severe Pruritus and Hypothermia as the Primary Manifestations of Human Herpes Virus-6 Encephalitis After Pediatric Cord Blood Transplantation Viral encephalitis has a reported incidence of 1.2-4% in prospective evaluations of allogeneic hematopoietic stem cell transplantation patients. [Bone Marrow Transplant] Open Cardiac Surgery in the First Hours of Life Using Autologous Umbilical Cord Blood This article describes the first clinical experience of complete repair of complex critical congenital heart diseases in the first hours of life using autologous umbilical cord blood. [Eur J Cardiothorac Surg] Protective Effects of Human Umbilical Cord Blood Stem Cell Intravitreal Transplantation Against Optic Nerve Injury in Rats Via intravitreal transplantation, human umbilical cord blood stem cells resulted in a significant increase in the survival of the retinal ganglion cells, and improved pathological changes in the rat retina, following traumatic optic neuropathy.
